Description

[Detailed explanation of the invention] Conventional methods for fixing the cut pile of artificial turf knitted fabrics to the knitted fabric include a method in which the pile knitting yarn is looped together with the ground chain knitting yarn, and a method in which the pile knitting yarn is knitted in a loop at the same time as the ground chain knitting yarn. There are two methods: inserting it into yarn to form a pile.

However, in the former method of forming and fixing piles, the cut piles tend to stand upright and are arranged too orderly on the wales, creating spaces between the wales, resulting in poor restorability and poor feel.

In order to eliminate the above-mentioned drawbacks, it is necessary to make the machine gauge finer or use a yarn with a large denier as the pile yarn.

However, if this is done, the amount of yarn used will increase, resulting in higher costs.

In addition, in the latter method of insertion and fixation, the pile is not securely fixed to the knitted fabric, so the cut pile is easy to pull out, and the cut pile becomes diagonal, which creates a space above the wale and improves recovery. Even weaker.

In this invention, the gauge of the knitting machine and the denier of the yarn to be knitted remain unchanged (the gauge of the knitting machine and the denier of the yarn to be knitted remain the same), but the cut piles are provided at a high density to increase resilience, and the fixation of the cut piles is ensured, so that the top surface of the pile group is always kept. The purpose of the present invention is to provide a high-density warp-knitted artificial turf fabric that can be kept in an orderly state.

The present invention consists of a cut pile 3 formed by cutting the pile of the pile knitting yarn 2 knitted at the same time as the ground knitting yarn 1, and a cut pile 4 formed by cutting the pile formed by inserting it into the ground chain knitting yarn 1. This invention relates to a high-density artificial turf warp-knitted fabric, which is characterized by having both the interlacing of wales and courses.

That is, a pile that loops simultaneously with the chain knitting yarn and a pile that is inserted into the chain knitting yarn are simultaneously generated at the intersection of the wale and the course, and then cut to provide a cut pile.

Therefore, a cut pile with twice the density of the conventional method is formed in an orderly manner.

At this time, the direction of the cut pile due to loop knitting is upright, and the direction of the cut pile due to insertion is diagonally upward.
Both the spaces created by the conventional weaving method and the spaces created by the insertion method are filled, and the tips of the cut piles appear dense, with high density, excellent resilience, and a remarkable feel. improved and durable,
Moreover, it has excellent effects such as less dust entering between the cut piles.
